Question

Population a current census shows that the population of a city is 3.5 million using the formula p= aert find the expected population of the city in 30 years of the growth rate r of the population is 1.5% a reaper prevents the current population in millions and the t represents the time in years

Answer 1

Answer: the expected population of the city in 30 years is 5470781

Explanation:

The population growth is exponential. The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 3.5 × 10^6

r = 1.5% = 1.5/100 = 0.015

t = 30 years

Therefore,

A = 3.5 × 10^6(1 + 0.015)^30

A = 3.5 × 10^6(1.015)^30

A = 5470781
